Cave diving is, as its name suggests, scuba diving in underwater caves. Superstar diver Jacques Cousteau is considered the father of the sport.
Not surprisingly, caves pose a number of dangers. In the event of an equipment failure, caves often prevent a quick ascent to the surface. They can also contain swift, unpredictable currents, and visibility can become severely compromised should a diver stir up sediment. Cave-diving deaths are a yearly occurrence: Even experienced divers fall victim to the caves' dangers.
